TOP-ROLL SADDLE.

Specification of Letters Patent.

Patented Nov. 5, 1907.

Application filed August 16, 1905. Serial No. 274.401.

To all whom it may concern:

Be it known that I, EZRA DIXON, a citizen of the United States, residing at Bristol, in the county of Bristol and State of Rhode Island, have invented new and useful Improvement in Top-Roll Saddles, of which the following is a specification.

My invention has reference to an improvement in top roll saddles and more particularly to an improvement in the bearings of top roll saddles.

Top roll saddles as heretofore constructed with straight or parallel bearings create considerable friction on the journals of the top rolls, thus requiring an excess of power to run the top rolls of a spinning machine and more oil than should be necessary to lubrirate the bearings of the top roll saddles.

The object of my invention is to eliminate friction (as near as possible) between the journals of the top rolls and the bearings of the top roll saddles, thereby I increasing the life of the saddles.

A further object of my invention is to reduce the amount of oil required to lubricate the bearings of top roll saddles, thereby reducing the cost of lubricating the same.

My invention consists in the peculiar and novel construction of a top roll sad'dle for spinning machines, said top roll saddle having a roller bearing or its equivalent adapted to bear on'the journal of a top roll, thus practically eliminating friction between the journal of the top roll and the bearing of the top roll saddle, as will be more fully set forth hereinafter.

Figure 1 is a side view of the front and back top roll saddles provided with my improved anti-friction or roller bearings and showing the same in their operative position on the journals of the top rolls of a spinning machine. Fig. 2 is an enlarged view looking at the underside of the front and back top roll saddles, show ingthe roller bearings in the same. Fig. 3 is an enlarged sectional view taken lengthwise through the front and back top roll saddles on line w w of Fig. 2, showing the means for oiling the roller bearings, and

, Fig. 4 is an enlarged transverse sectional view through the front top roll saddle taken on line X X of Fig. 1, showing the construction of the roller bearing in the same.

In the drawings, a a indicates the journals of the top rolls, b the back saddle, c the front saddle, d d oil grooves in the front and back saddles, c 6 oil wicks in the oil grooves, f weight strap, and g g the roller bearings of my improved front and back top roll saddles.

I The back and front'saddles b and c are each confrom the grooves d d to the cavities g 9 formed in the underside of the saddles, as shown in Fig. 3. I The lower edges of the side walls g g are shaped to conform to the journals (1 a of the top rolls. The saddles saddles and secured to the saddles in the countersunk portions 9 g by the screws g g as shown in Fig. l and Fig. 4. The rolls g g are rotatably secured in the bearings g g formed in the side walls g g by boring two holes through the countersunk side wall 9 and partly through the opposite side wall 9 The bearings g g thus formed intersect the lower edge of the side walls g g allowing the rolls 9 9 when secured in the bearings g g by the plate 9 to project slightly through the lower edge of the side walls g7 g as shown in Figs. 3 and 4, otherwise the front and back top roll saddles may have the construction of any of the wellknown forms of top roll saddles. The ends of the wicks e e project through the holes 61 d onto the rolls 9 g for lubricating the same.

e e are oiled by the operator in the usualway. The wicks leading to the roller bearings g g lubricate the bearings for a longer period with one oiling than has heretofore been done and the roller bearings 'g g prac tically eliminate friction between the journals of the top rolls and the bearing of the top roll saddles, thus reducing the power required to run the top rolls.

Having thus described my invention, I claim as new and desire to secure by Letters Patent;-
